I’m not sure if this is fully kosher, but suit yourself : #include "TAxis.h" #include "TH1.h" #include "TArrayD.h" Double_t ScaleX(Double_t x) { Double_t v; v = 10 * x + 100; // "linear scaling" function example return v; } Double_t ScaleY(Double_t y) { Double_t v; v = 20 * y + 200; // "linear scaling" function example return v; } Double_t ScaleZ(Double_t z) { Double_t v; v = 30 * z + 300; // "linear scaling" function example return v; } void ScaleAxis(TAxis *a, Double_t (…
